A team of scientists was called to the Yamal Peninsula in Siberia to look into the appearance of a 262-foot wide crater this week.
It was already confirmed that the crater was not a result of a meteorite or a UFO, so results may be disappointing to some, according to the Daily Mail.
A team of scientists from the Scientific Research Center of the Arctic, led by Andrei Plekhanov determined that the most likely result of the crater was a "build-up of excessive pressure underground, due to the region's changing temperatures," according to Daily Mail.
The researchers collected samples of soil, air, and water from the scene of the enormous crater to try figuring out where the hole came from.
Guesses made by commenters on YouTube videos and articles posted by media outlets around the world included a meteorite crash, UFO landing site, global warming, a gas explosion, or a sinkhole caused by collapsing rock.
Plekanov confirmed that the darkened sides of the crater showed intense temperatures caused by something igniting or exploding. There were no traces of something striking the area however, according to the Daily Mail.
Plekhanov said 80% of the crater appeared to be made of ice, which meant a meteorite didn't crash down, nor is it a UFO landing spot.
Some still considered a gas explosion to be the most likely reason since the Yamal Peninsula is one of the most geologically young places on Earth. It contains the largest natural gas reservoir in Russia as well, according to the Daily Mail.
The researchers assessed global warming as the cause for the immense crater.
They believe changes in the environment resulted in the releasing of gases under the surface and forced the ground to explode like a Champagne cork.
Anna Kurchatova, a researcher from the Sub-Arctic Scientific Research Center confirmed Plekhanov's belief that global warming was the cause of the crater's appearance.
She said that a mixture of water, salt, and gas ignited and caused an underground explosion.
The Yamal Peninsula is Russia's main production area for gas supplied to Europe and is mainly undeveloped, which made the appearance of the crater so odd.
